Attack-Flow Graph

Executive Summary

This vulnerability in the Frappe web application framework involves a path traversal issue via the download_backups feature. Before versions 16.19.0 and 15.109.0, the application did not properly harden this functionality, allowing an attacker to potentially access files outside the intended directory.

Impact Analysis

The path traversal vulnerability could allow an attacker with certain privileges to download arbitrary files from the server, potentially exposing sensitive information or system files that should not be accessible.

Mitigation Strategies

To mitigate this vulnerability, update the Frappe framework to version 16.19.0 or later, or 15.109.0 or later, as these versions contain the fix for the path traversal issue via download_backups.
